Powers:The Star-Stalker is approximately 16 feet tall and possesses superhuman strength and durability. Its base level is superhuman to an unknown degree (strong enough to catch Thor in mid-flight with its tail and hurl him away), but its power is amplified by absorption of energy. Its tail could be used as a fifth limb in combat.
The Star-Stalker could travel through interplanetary space unaided and unsupported. Despite being reptillian, its mutant nature somehow provided with the ability to resist the near absolute zero cold, as well as the low pressures and lack of oxygen. Upon arriving on a planet, it could then form an ionic coccoon and metamorphosize into a form of "pure ionic combustion," able to metabolize large amounts of energy. In this form, ions flow into it, feeding it. It can apparently drain the energy from an entire planet. It is presumably this massive energy store which it uses to travel between planets.
However, in its ionic combustion state, while it can absorb massive amounts of certain forms of energy, it retains a weakness to great heat, which can weaken or even destroy it. Even ordinary levels of heat cause it some pain, and it prefers to act nocturnally.
After its death, the Star-Stalker's power source was the magical energy derived from Lloigoroth and other demons.

Bio:The Star-Stalker is a mutant member of the Vorm race. Its full history is unknown, but it apparently sired a son at some point. The Star-Stalker spent most of its life traveling from planet to planet, feeding on and draining the planet's energies, and then moving on. For the most part, the Stalker traveled to unpopulated worlds, avoiding the heat of warm-bodied people and the warmth of planets that supported them.
